Question

In an experiment, Theresa measured 15.05 mL of water. She must have used a flask that had markings every 25 mL. beaker that had markings every 20 mL. buret that had markings every 0.1 mL. graduated cylinder that had markings every 1 mL.

Answer 1

Buret that had markings every 0.1 mL

Step-by-step explanation:

Answer 2

Buret that had markings every 0.1 mL

Step-by-step explanation:

Consider the measurement of the water which is 15.05 mL. Then consider the measurement marks of each of the instruments or apparatus used.

The clue there is 0.05 mL. Which instrument would be able to measure 0.05 precisely?

The best instrument used in this scenario that would be able to measure closest to 0.05 is the Buret, which has markings 0.1mL because the markings are the closest to 0.05mL, which would be half-way to the next mark.

In an experiment you need to consider precision, and all other apparatus given cannot give a precise measurement.
